Specification
C601 / 602 is a kind of two-component foaming and spraying grouting material made of organic polymer, which has the characteristics of fast foaming, large foaming multiple and non combustion. It is suitable for spraying surface sealing and rapid construction of protective layer in coal mine roadway. The slurry is packed in two-component and independent packaging, so there is no need to weigh and prepare the slurry on site. As long as component A and component B are mixed in a volume ratio of 1:1 by strong air pressure of the equipment, they can be sprayed.
